特征

  • I²C总线控制型IC卡接口采用TFBGA64封装
  • 电源电压范围：2.7 V至5.5 V
  • 专用的微控制器接口电源电压(VDD(INTF))
  • TDA8026处于非激活状态时，关断模式确保具有极低的功耗
  • 卡槽非激活时触发可编程低功耗模式
  • 通过DC-DC转换器生成VCC(n)：可完全加载两个卡槽，另外三个处于低功耗模式
  • 两个时钟输入针脚：CLKIN1用于卡槽1，CLKIN2用于卡槽2至5
  • 微控制器侧具有两条透明的I/O线，一条用于卡槽1，另一条用于卡槽2至5
  • 五条受保护的半双工双向缓冲I/O线，限流为± 15 mA，最大频率为1 MHz
  • 两个I²C总线受控型辅助I/O线
  • 所有卡槽提供VCC(n)调节功能(ICC ≤ 55 mA)：
    • 5 V、3 V或1.8 V ± 5 %
    • 对于5 V卡而言，电流尖峰为40 nAs至20 MHz，可控制上升和下降时间
    • 限流约为100 mA
  • 针对所有卡片接触的热保护和短路保护
  • 自动激活与取消激活序列：发生短路、卡片移走、VDD(INTF)、VDD或VUP电压下降等事件时，可通过软件或硬件初始化
  • 卡片端具有高达6 kV的增强静电放电(ESD)保护功能
  • 20 MHz时钟输入
  • 生成高达20 MHz的卡片时钟且具有1/2/4/5分频，同步频率可变化如下：
    • 停止、高电平或低电平
    • 在卡片低功耗模式下，时钟频率范围为1 MHz至2.2 MHz
    • 针脚CLK(n)具有限流功能
  • RST(n)信号线限流为20 mA，由异步卡上的嵌入式可编程时钟脉冲计数器控制，或由同步卡上的寄存器控制
  • 兼容ISO 7816-3和EMV 4.2支付系统
  • VDD(INTF)电源电压监控器确保微控制器和电路之间可正常通信；阈值内部固定，或使用外部电阻桥设置
  • VDD电源电压监控器可在上电时抑制尖峰，在关断时紧急取消激活；阈值内部固定
  • 内置17.8 ms（典型值）去抖系统（卡槽1和2），提供卡片存在性输入
  • 一个中断信号(IRQN)

Target Applications

  • 销售点终端
  • 多SAM接触式读卡器
